ENTSOG Implementation and Monitoring Report 2017 - Balancing Network Code

2.3 NOMINATIONS (CHAPTER IV OF BAL NC)

Nominations are a central part of BAL NC since the information received by TSOs from a Network User’s gas nomination is essential to the safe and efficient balancing of the network. This information enables TSOs to also predict where and to what extent gas imbalances are likely to occur. BAL NC sets out basic nomination and re-nomination rules for TSOs and shippers to follow when nominating and re-nominating gas quantities.

All 25 countries (AT, BE/LU, BG, CZ, DE, DK, EE, EL, ES, FR, HR, HU, IE, IT, LT, LV, NL, PL, PT, RO, SE, SI, SK, UK-GB and UK-NI) have re- ported the implementation of nomination rules at all IPs by 1 October 2017.

2.3.1 Hourly Re-nomination Cycle and Standard Re-Nomination Lead-time of Two Hours

24 countries (AT, BE, BG, CZ, DE, DK, EE, EL, ES, FR, HR, HU, IE, IT, LV, LT, NL, PL, PT, RO, SE, SI, SK, UK-GB and UK-NI) reported that the hourly re-nomination cycle and standard re-nomination lead-time of two hours are applied at all IPs according to Article 15(3) of BAL NC by 1 October 2017.

Luxembourg stated that at the IP Remich between Germany and Luxembourg the re-nom- ination lead time is two hours and 15 minutes. The additional time is used by Creos Luxembourg to re-nominate in case suppliers do not fulfil their nominations obligations/restrictions based on the forecast offtake at this IP.

2.3.2 Nomination and Re-nomination Provisions for Bundled Capacities

Where TSOs offer bundled capacities at IPs, the nomination and re-nomination provisions according to Article 12(3) of BAL NC shall also apply to single nominations and re-nominations for bundled capacity products. 11 Countries (CZ, ES  1) , FR, IE, IT, NL, PL, PT  1) , SI, SK, UK-GB and UK-NI) have a single nomi- nation established at all interconnection points. 6 Countries (AT, BE/LU, DE, HR and RO) coop-

erated with the adjacent TSO(s) for the purpose of implementing nomination and re-nomination rules for bundled capacity products at intercon- nection points and basically agreed on the main parts of the process also there are still some details to finalise. DK stated that a single nomi- nation will be implemented later this year. Hungary stated that single nomination is availa- ble at HU/HR and HU/RO and under discussion at HU/AT.

1) The TSO cooperation ended up with the establishment of single nomination at both France and Portugal Interconnection Points after the survey period.
